I know it's a bit odd to bump this thread back up, but I didn't see a point in creating a new topic.
I'm listening to Sing, by Annie Lennox. It's a great song that's about women, and how they shouldn't disrespect themselves. It's also about combatting HIV in Africa. A whole chorus of female singers take part, including Joss Stone and Madonna.
This is the best video I could find.

It's not all fancy with moving pictures or anything, but the song's what counts.
